<h1 id="PLUGINS"><a class="permalink" href="./App::Prove.html#PLUGINS">#</a>PLUGINS</h1>

<p><code>App::Prove</code> provides support for 3rd-party plugins. These are currently loaded at run-time, <i>after</i> arguments have been parsed (so you can not change the way arguments are processed, sorry), typically with the <code>-P<i>plugin</i></code> switch, eg:</p>

<pre><code class="plaintext">prove -PMyPlugin</code></pre>

<p>This will search for a module named <code>App::Prove::Plugin::MyPlugin</code>, or failing that, <code>MyPlugin</code>. If the plugin can&#39;t be found, <code>prove</code> will complain &amp; exit.</p>

<p>You can pass an argument to your plugin by appending an <code>=</code> after the plugin name, eg <code>-PMyPlugin=foo</code>. You can pass multiple arguments using commas:</p>

<pre><code class="plaintext">prove -PMyPlugin=foo,bar,baz</code></pre>

<p>These are passed in to your plugin&#39;s <code>load()</code> class method (if it has one), along with a reference to the <code>App::Prove</code> object that is invoking your plugin:</p>

<pre><code>sub load {
    my ($class, $p) = @_;

    my @args = @{ $p-&gt;{args} };
    # @args will contain ( &#39;foo&#39;, &#39;bar&#39;, &#39;baz&#39; )
    $p-&gt;{app_prove}-&gt;do_something;
    ...
}</code></pre>

<p>Note that the user&#39;s arguments are also passed to your plugin&#39;s <code>import()</code> function as a list, eg:</p>

<pre><code>sub import {
    my ($class, @args) = @_;
    # @args will contain ( &#39;foo&#39;, &#39;bar&#39;, &#39;baz&#39; )
    ...
}</code></pre>

<p>This is for backwards compatibility, and may be deprecated in the future.</p>
